Dual Universal AGC-Video Amplifier System Model H-132-6A


Dual Universal AGC-Video Amplifier System
Model H-132-6A

The model H-132-6A AGC-Video Amplifier meets today’s high frequency band instrumentation requirements. Each AGC-Video Amplifier has six separate isolated outputs for driving several devices from a common source. Two amplifiers are housed in a single Model VS-106 chassis with a common power supply. Each AGC-Video Amplifier is a removable plug-in unit with front panel meter, test points and controls.

The AGC-Video Amplifier has two modes of operation: AGC or Video, switch selectable. In the AGC mode of operation, the gain of the amplifier is the input amplitude dependent and will maintain a constant output amplitude of one volt RMS over the dynamic input range of 1V peak-to-peak to 7V peak-to-peak. The AGC amplifier is excellent for use with tape recorders or other devices where constant output amplitude is desired. In the Video mode of operation, the AGC action is defeated and the amplifier operates as a straight DC video amplifier with adjustable gain. In both modes of operation, the six amplifier outputs have low output impedance and are capable of driving terminated 75 ohm coaxial cable.

The flexibility of the AGC-Video Amplifier meets a wide variety of today’s Instrumentation requirements.
